[1]\n\nBecause the inode bitmap is corrupted, an inode with an inode number that\nshould exist as a \".nilfs\" file was reassigned by nilfs_mkdir for \"file0\",\ncausing an inode duplication during execution.  And this causes an\nunderflow of i_nlink in rmdir operations.\n\nThe inode is used twice by the same task to unmount and remove directories\n\".nilfs\" and \"file0\", it trigger warning in nilfs_rmdir.\n\nAvoid to this issue, check i_nlink in nilfs_iget(), if it is 0, it means\nthat this inode has been deleted, and iput is executed to reclaim it.\n\n[1]\nWARNING: CPU: 1 PID: 5824 at fs/inode.c:407 drop_nlink+0xc4/0x110 fs/inode.c:407\n...\nCall Trace:\n <TASK>\n nilfs_rmdir+0x1b0/0x250 fs/nilfs2/namei.c:342\n vfs_rmdir+0x3a3/0x510 fs/namei.c:4394\n do_rmdir+0x3b5/0x580 fs/namei.c:4453\n __do_sys_rmdir fs/namei.c:4472 [inline]\n __se_sys_rmdir fs/namei.c:4470 [inline]\n __x64_sys_rmdir+0x47/0x50 fs/namei.c:4470\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x77/0x7f","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/284760b320a0bac411b18108316939707dccb12b","https://git.kernel.org/stable/c/55e4baa0d32f0530ddc64c26620e1f2f8fa2724c","https://git.kernel.org/stable/c/5d4ed71327b0b5f3b179a19dc3c06be9509ab3db","https://git.kernel.org/stable/c/901ce9705fbb9f330ff1f19600e5daf9770b0175","https://git.kernel.org/stable/c/912188316a8c9e41b8c1603c2276a05043b14f96"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:58:20.756570362+00:00"},"epss":{"cve":"CVE-2024-53690","score":0.00256,"percentile":0.17301,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
